<p><P>PROBLEM TO BE SOLVED: To provide a fuel cell that improves current density and its maintenance rate when at least glucose dehydrogenase and diaphorase are fixed on a negative electrode by a fixing material consisting of poly-L-lysine and glutaraldehyde. <P>SOLUTION: The fuel cell has a structure in which the positive electrode 2 and the negative electrode 1 are opposed through an electrolyte layer 3, and the negative electrode 1 has at least glucose dehydrogenase and diaphorase fixed by a fixing material consisting of poly-L-lysine and glutaraldehyde. The mass ratio of poly-L-lysine and glutaraldehyde in the fixing material is 5:1-80:1, the mass ratio of glucose dehydrogenase and diaphorase is 1:3-200:1, and the average molecular weight of the poly-L-lysine is made≥21,500. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
